Kotlin on Android now officially announced at Google I/O

At the Google I/O keynote, the Android team announced first-class support for Kotlin. This is a great step for Kotlin, and fantastic news for Android developers as well as the rest of our community. They’re thrilled with the opportunities this opens up.

For Android developers, Kotlin support is a chance to use a modern and powerful language, helping solve common headaches such as runtime exceptions and source code verbosity. Kotlin is easy to get started with and can be gradually introduced into existing projects, which means that your existing skills and technology investments are preserved.

Starting now, Android Studio 3.0 ships with Kotlin out of the box, meaning Android developers no longer need to install any extras or worry about compatibility. It also means that moving forward, you can rest assured that both JetBrains and Google will be supporting Android development in Kotlin.

In case you are concerned about other platforms that Kotlin supports (Kotlin/JVM for server and desktop, Kotlin/JS and Kotlin/Native), please be sure that they are as important for us as ever. Our vision here is to make Kotlin a uniform tool for end-to-end development of various applications bridging multiple platforms with the same language. This includes full-stack web applications, Android and iOS clients, embedded/IoT and much more.

Programming languages are just like human ones: the more people speak a language, the better. First-class support on Android will likely bring more users to Kotlin, and they expect the community to grow significantly. This means more libraries and tools developed in/for Kotlin, more experience shared, more Kotlin job offerings, more learning materials published, and so on. They are excited to see the Kotlin ecosystem flourish!

They will be partnering with Google to create a non-profit foundation for Kotlin. Language development will continue to be sponsored by JetBrains, and the Kotlin team (over 40 people and second largest team at the company) will operate as usual. Andrey Breslav remains the Lead Language Designer, and Kotlin will be developed under the same principles as before. They’ll keep our design processes open, because your feedback is critical for us in moving Kotlin in the right direction.

If you’re at Google I/O, make sure you stop by one of the ‘Kotlin talks on the schedule. And of course, don’t forget to register for ‘KotlinConf’ in San Francisco in November. It will be an amazing event!

Is Kotlin going to become primarily focused on Android?

One of Kotlin’s goals is to be a language that is available on multiple platforms and this will always be the case. It will keep supporting and actively developing for Kotlin/JVM (server-side, desktop and other types of applications), and Kotlin/JS. They are working on Kotlin/Native for other platforms such as macOS, iOS and IoT/embedded systems.

How does this impact Kotlin’s release cycles?

Kotlin will continue to have its own independent release cycle from that of Android or Android Studio. The projects remain completely independent. Obviously there will be close collaboration between the product teams to make sure that Kotlin is always working correctly in Android Studio.

Who’s going to work on the Android Studio plugin?

JetBrains will continue to work on the Android Studio plugin, collaborating closely with the Android Studio team.

Will this affect the support for IntelliJ IDEA, Eclipse or Netbeans?

No. Kotlin continues to be a language that targets multiple platforms and support for other IDE’s will continue to be provided as before. Obviously emphasis will be placed on IntelliJ IDEA with hopefully community contributions on the other ones.

Will this affect support for macOS or iOS?

No. They still have plans to support both of these systems with Kotlin/Native and nothing has changed in this regard.

Is JetBrains going to be acquired by Google?

No. JetBrains has no plans of being acquired by any company. JetBrains is and continues to be an independent tool vendor catering to developers regardless of their platform or language of choice.
